Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664340, here are decompositions:

11 + 8664329 = 8664340
23 + 8664317 = 8664340
29 + 8664311 = 8664340
233 + 8664107 = 8664340
317 + 8664023 = 8664340
353 + 8663987 = 8664340
479 + 8663861 = 8664340
521 + 8663819 = 8664340

Showing the first eight; more decompositions exist.
